The Mill No. 1 is a relatively modern polder mill located on Achtermiddenweg in the town of Aarlanderveen. It was built in 1924, to serve the old 450 hectare West Aarlanderveen polder. The mill was bought by the Aarlanderveen Mill Foundation in 1963, and is still in use as a polder mill today. The Mill No. 1 is one of four mills in the Aarlanderveen area, and is a fine example of the role of windmills in modern day Holland.
